Hi, I’m attempting to make a simple train and I can’t get it to work.

The “Chassis” is the part I’m trying to move and then the track is the path I want it to stay on.

I’ve tried using the Linear Constraint but I’m really bad with physics and constraints.

I could really use some help!

Hello, you can use a ‘VectorForce’ constraint, or attempt to change the CFrame with ‘stepped’ event of ‘run service’, other contraints really I don’t know. If you still need help, please tell me wich method of those that I have given you prefer to use, to explain it with detail.
